Does i work, or does it explode?

[lyan]

Can i charge my 3650 with an old square nokia 3310-charger,
or is it not the same power or something?

[Jesal]

yea u can. all noki have same chargers.

[gophermaster]

Yeah, they have the same specifications, they just look a little different.

[ti3ucuong]

no.the charge that come with 3650 is way faster then 3310. the old charge can be use but it take longer for u to charge ur fone

[gophermaster]

The charger that came with my N-Gage seems to charge at the same speed as the charger I got with my 3310.

[tzeonn]

well, it shld work fine, but if u touch ur charger and its burning hot, u better not use tt charger, otherwise its fine.

[Iceman5]

my dad has an old nokia phone... dont even know the name... 5xxx something, and when he tested my charger for the 6600 it ses "cannot charge" on the display

[tzeonn]

well, i got those big none orig chargers, i charged my fone, and after charging, it was v v hot, so i dared not use none orig chargers again.

The speed of energy can differ? I don't think so.. Let me reply with another quote:

There is a specific speed of energy propagation through space we call the speed of light in vacuum and label c.
I guess the icon for this topic has a reason after all :D
The phenomenon of the speed of light must be so spectacular/popular, there exists a website only about that!
http://www.what-is-the-speed-of-light.com/
Pretty nice eh? :D
299,792,458 m/s (metres per second)
... Now That's FAST!
My point = It's always the same speed.

Anyway! I charge my N-Gage with several chargers (from my dad, my gf, her mom, her bro, and everywhere I need and can find one when I'm not carrying mine) and I've never experienced any problems whatsoever. And if it does explode.. Hell! It's ensured! :lol:

ps. Don't take this post to serious. I don't know for sure if the scientific "facts" are 100% correct. I'm only human! :-P I've just took some google time and presumed the equation according to the sources I've found. Any scientists hangin' around on these forums? :D

If you charge your 3310 with an 3650 charger, the "battery full" message appears after about 15 minutes! :D

[Wouwz]

IT DOES MATTER, the amount of Volts and Amperes is very important, if the charger charges at a lower Volt or Ampere than the phone it's no problem.

If it's higher u OVERCHARGE (duh) and ur battery can explode or leak

That's a bigger charge, not a faster one ;)

I'll start believing all that if someone can prove it that a official nokia phone has exploded using a official nokia charger. (pictures please! :D)

Yeah, the speed of light is around that, lets just call it 3.00 x 10^8 m/s (through a vaccuum). But you see, where you are wrong is that light only travels as fast as the medium will allow, say, if light was travelling through diamond, then speed of light is halved (around that).

But that aside, the speed would only be how long it takes for the electrons to come in contact with the battery from the transformer in the charger. The speed can be as fast as it wants, but if there is no electrons then obviously the battery would not charge, therefore the amps involved in the charging process is needed. So if the amperes in the charges were different then one would charge faster than the other.

Take this analogy for example, its like filling up a bucket of water, the faster the water flows out (amps) the faster the bucket will fill up (battery). It's just an example, electricity sort of works like that, but not exactly.

[gophermaster]

The speed of energy can differ? I don't think so..


Of course the speed of energy differs, take sound energy for example, as sound energy is a mechanical wave it requires a medium to travel through, and as the mediums change, so does the speed of sound. Eg, Speed of sound in Carbon Dioxide is around 260 ms-1, and the speed of sound in glass is around 5500ms-1. So yeah, there is no definate speed of energy. What that site said was that there was a definate speed of light through a vaccuum.

An old nokia 3310 charger I have is rated at
3.7V at 355mA = 4.055W

where as my 6600 one is
5.7V at 800mA = 4.56 W

So yes, there is a difference. The old one will probably work with the new phones but charing more slowly. The reason why it gets so hot is that the phone is trying to draw more current than the charger can produce, hence the charger works harder and so heats up.

Old phones may or may not take a liking to the increased spec of the new charger however, depends on their design...


My new charger makes a high pitch noise when on (with or without phone connected). anyone heard of that happening?

[FunkyG]

@ GopherMaster

Dang man, where did you learn all that? Anyway, thx! You've made me a bit smarter ;)

So.. What if you would remove the adapter between the power connector to the phone and the plug in the electricity (directly transferring 220-240volts (standard in Belgium)). Wouldn't that be like an INSTANT CHARGE?! :lol: haha, would be pretty awsome tough..

[Musicb0ffin]

Erm... I don't think that would be a good idea... if you got 240V going it at 13amps, thats over 3kW of power, and considing the chargers are giving out 5W, I think your fone would be screwed before you had a chance to run away. Still, in controlled conditions, it could be fun.

Dont forget to take some pictures lol :lol:

Some of the older (much older) phones actually were 5.7v and some higher.
The older chargers were just basically dropdown transformers also the cheap imitation chargers are as well but the new chargers are switchmode power supplies thats why you get the whistle. Unless youve got a little man inside looking for his dog :lol: You can normally tell by the weight as the new ones (switchmode) dont have the big transformer inside so are lighter. :)

[Musicb0ffin]

Thinking about it, don't nokia batts monitor the temperature of them, so thats how they know when they are fully charged? That would mean you could step up the voltage a bit to speed up charging. Still, i dunno how that would affect the life of the battery.

With the charging the phone off the mains idea, i don't think it would be that impressive. The tracks on the circuit board would probably just burn out, so you would get a bit of smoke, but nothing spectacular. Only one way to find out tho!! :p

I don't think that it is reasonable to often charge your phone without the proper charger. In my country (Greece) a woman tried to do this, but her mobile (3310) exploded during the night while she was charging it!!!


I mean how wicked is that???

[aussie]

I always thought nokia chargers were universal.. anyway i use ACP 12x chargers for all my phones, and havn't had any problems as yet..
Cheers

[Space monkey]

A few months ago there exploded some nokia phones in the netherlands, Nokia claims that those people where using imitation battery's.

I doubt this...

Weird......... They said that here too.... Something about safety circuits that imitation accessories dont have.

Same company, same excuses...

[Musicb0ffin]

Don't nokia batts have a temp sensing circuit, so that when it starts getting hot during charging, it knows to stop chargin cuz the batt is done? Someone was saying that with fake batts, this circuit has been removed to add extra capacity to the battery. If this is true, what nokia are saying would make sense.

I know there are 2 resisters in nokia batteries but I cant see how that could sense temperature more current charging protection I would have thought but not sure :-?
Maybe some of the experts (electronics) on here could comment :)

[Musicb0ffin]

Yeah, 2 resitors form a temp sensing circuit. Can't remember whats its called... and i do physics :s Someone's gotta know what its called. Thats gonna annoy me now...

I think what you are referring to is the wheatstone bridge but that is made up of four resisters. The 2 resisters dont seem to be battery temperature controller otherwise it wouldnt be needed in griffin conectors as they (the resisters) are not in direct contact with either battery or phone so couldnt monitor temperature :-?

[Musicb0ffin]

Thermocouple is what i'm thinking about. Praps i'm wrong, i dunno. I haven't had a close look at how the batteries are set up.

[FU_Too]

Well Ive only opened batteries for 6800 (2 resisters 47k 68k) 8210 (47k 22k) 3310 (47k 22K) and 5146 and have not seen any thermocouples or themisters and they seem to be on charging side going to grnd so if anyone can tell us the purpose as dosnt look like temp control :smile:

[Space monkey]

If my 6600 exploses i'll sue Nokia's ass off :D
